Once you have a chance to listen, try gently wiggling the cable connectors on the crossover boards. Mine were very flaky and caused no end of scratchy sounds and driver dropouts. I found a similar inline version of the female connector but had to add some short wires between it and the PC board but it solved my troubles. I may have been able to trim the wire solder loops on the connector and get it to fit into the board but decided to just use the short wire jumpers. I also changed the tweeter series cap to a WIMA, the red one in the pic, but I don't think I can hear any difference.
Have fun.
Thanks for the tip! Very helpful!
At the moment, I don't even know where to start with disconnection and moving speakers. I think I'm just first going to give the cabs a light block sanding and oil. That will sooth my mind while I ponder the cave situation!
